Description
本発明は、線材の張力測定装置に関し、特に例えば、電線等のケーブルやワイヤロープなどの被測定線材の張力を測定する線材の張力測定装置に関するものである。 The present invention relates to a wire tension measuring device, and more particularly to a wire tension measuring device for measuring the tension of a wire to be measured such as a cable such as an electric wire or a wire rope.
ケーブルの地中管等への入線工事におけるケーブルなどの被測定線材の張力を測定するために用いられる、測定装置としてプーリテンションメータがある。 There is a pulley tension meter as a measuring device used for measuring the tension of a wire under test such as a cable in the work of entering a cable into an underground pipe or the like.
実公平６−９３４９ Real fairness 6-9349
ケーブルの地中管等への入線工事におけるケーブルの引入れは、管路内面とケーブル外装との間に摩擦が発生し、管の屈曲部ではケーブルの引入れ張力が増大し、ケーブルに対し側圧を生じる。
この側圧が限度を超えると、ケーブルを構成するシース、銅テープなどのシールド材、絶縁介在物、芯線などを損傷する恐れがある。
そこで、ケーブルの引入れ作業中に張力監視を行い、張力を管理することが必要となり、ケーブルの張力を測定しながら、入線工事をすれば、ケーブル損傷防止に繋がる。
しかしながら、張力測定装置は、車輌で工事現場に持って行くことが必要であるが、ケーブルの地中管等への入線工事をする車輌に裾え付けられているため、直接受ける衝撃・振動から張力測定装置の損傷を防ぐ必要がある。
張力測定装置のみ点検・取替が可能となり、メンテナンスが容易に行える張力測定装置を求められている。
既設電線あるいはワイヤなどが布設からの年月の経過によって、伸縮している可能性があるため、当初の張力（規定張力）で張られていない可能性があるので、既設電線あるいはワイヤなどの布設された被測定線材の張力を測定する必要がある。
この発明は、上記事情を鑑みてなされたもので、運搬が容易で、メンテナンスが容易に行える、被測定線材の張力を測定して被測定線材の損傷を防ぐことができる、張力測定装置を提供することである。When the cable is pulled into the underground pipe, etc., friction is generated between the inner surface of the pipeline and the outer surface of the cable, and the pull-in tension of the cable increases at the bent part of the pipe, causing lateral pressure on the cable. Produces.
If this lateral pressure exceeds the limit, there is a risk of damaging the sheath, shielding material such as copper tape, insulating inclusions, core wire, etc. that make up the cable.
Therefore, it is necessary to monitor the tension during the cable pull-in work and manage the tension, and if the wire entry work is performed while measuring the cable tension, the cable damage can be prevented.
However, although it is necessary to bring the tension measuring device to the construction site by vehicle, it is attached to the vehicle that is going to enter the underground pipe of the cable, so it is directly affected by impact and vibration. It is necessary to prevent damage to the tension measuring device.
There is a demand for a tension measuring device that can be inspected and replaced only with a tension measuring device and that can be easily maintained.
Since the existing electric wire or wire may be expanded or contracted due to the passage of time from the laying, it may not be stretched at the initial tension (specified tension), so the existing electric wire or wire is laid. It is necessary to measure the tension of the wire to be measured.
The present invention has been made in view of the above circumstances, and provides a tension measuring device capable of easily transporting and easily performing maintenance, measuring the tension of the wire under test and preventing damage to the wire under test. It is to be.
